Design and implementation of efficient directory facilitator for context-aware service discovery

Abstract

Multi-agent technologies are essential in realizing the upcoming ubiquitous environment. In the multi-agent environment, each agent has its own set of services and stores these services in the service repository of the multiagent system. By using this repository, the user can retrieve the most appropriate service. In this paper, we propose an efficient service repository architecture that can improve the existing repository by using context inferencing, context filtering, user-predefined policies, and the categorized tree. An advantage of the proposed architecture is that the user can obtain more suitable services than existing approaches about service discovery. © Springer-Verlag Berlin Heidelberg 2007.
